Have a project in mind?
Zeven designs clean, scalable, and intuitive GraphQL schemas that accurately model your business domain. We define types, queries, mutations, subscriptions, and relationships with careful attention to naming conventions, nullability, pagination patterns, and versioning strategy. A well-designed schema is the foundation of a great GraphQL API — and Zeven ensures yours is built to last and easy for client teams to consume.
Zeven builds high-performance GraphQL servers using Apollo Server, GraphQL Yoga, Mercurius, and Pothos. We implement resolvers, data loaders, custom scalars, directives, and middleware with clean, maintainable code. Our servers are optimized for performance, security, and reliability — handling complex nested queries efficiently while protecting against common GraphQL vulnerabilities.
Zeven guides businesses through the migration from REST APIs to GraphQL with a phased, low-risk approach. We audit your existing REST endpoints, map them to a GraphQL schema, implement a wrapping layer to preserve compatibility during transition, and incrementally shift client teams to the new API. Our migration playbook minimizes disruption while delivering the flexibility and developer experience benefits of GraphQL quickly.
Zeven designs and implements federated GraphQL architectures using Apollo Federation and GraphQL Mesh. We decompose large monolithic graphs into independently deployable subgraphs owned by separate teams, then compose them into a unified supergraph. This approach enables true API ownership at the team level while giving consumers a single, coherent graph. Our federation expertise covers schema composition, entity resolution, subgraph routing, and gateway configuration.
Zeven identifies and resolves GraphQL performance bottlenecks including N+1 query problems, over-fetching, resolver inefficiencies, and query complexity issues. We implement DataLoader batching, query depth limiting, field-level caching, persisted queries, and response caching strategies. Our performance optimization engagements deliver measurable improvements in API response times, database query counts, and server resource utilization.
Zeven implements robust security and authorization layers for GraphQL APIs. We design field-level and type-level access controls, integrate authentication middleware, implement query depth and complexity limits, rate limiting, and introspection controls to prevent abuse. Our security reviews identify common GraphQL vulnerabilities including injection attacks, excessive data exposure, and denial-of-service risks — and implement mitigations that keep your API secure.
Zeven helps frontend teams adopt GraphQL effectively with Apollo Client, urql, and TanStack Query integrations. We set up type-safe query generation using GraphQL Code Generator, design fragment-based component data requirements, implement optimistic updates, cache normalization strategies, and real-time subscriptions. Our frontend GraphQL consulting empowers React and Next.js teams to fetch exactly the data they need with excellent developer experience.
Zeven designs and implements real-time GraphQL subscription systems using WebSockets, Server-Sent Events, and GraphQL over HTTP.
